Laura's baby boy, Christopher, wouldn't stop crying. She just needed a few minutes of quiet to feel refreshed from the screaming. The only thing she could think to do was put Christopher down for a nap. At first, he got extremely fussy, kicking his legs and getting louder. He wasn't a happy baby. Laura rocked him and, sure enough, he started to fall asleep. She rubbed his back in his crib and his crying stopped. She popped his pacifier in his mouth and he was out like a light. Laura sat down, smiling, and took a deep breath.
